We just had a customer chargeback seven months of Ali Pashaei's training. It's difficult to challenge these things without proof that they consumed the materials.
Going forward I will implement better tracking to defend against this non-sense.
In the mean time, we are publishing a page with Chargeback Offenders so other businesses can be alerted to this person's behavior and not do business with them. We hope to slow down fraudulent transactions.
